Hello there Jayjay, long time no see
welcome back.
There are two things :
if you talk about the game : you can dump it on any console (or even use illegal sharing website) the dump is not tied to the console.
If you tail about the DLC : the DLC data is not tied to the console either, but the game needs to get access to the list of unlocked DLC on the console, even if you have the DLC data for loadiine on your SD card it will not work on a console which doesn't have that DLC installed on the console at the same time. The console unlock the DLC only if it see that it's unlocked and available on the console, then loadiine can load it from SD (it can't load it from internal that's why you need to have both the DLC on internal and external).
You need to be able to launch the game to get the folder's access rights.
You don't need to play the game entirely or dump it entirely to get or install the DLC.
If the game boots, but has issue reading later in the game, that's fine.
If it doesn't boot anymore, you won't be able to install the bought DLCs, nor dump them for loadiine.
